"Kwabo bangengobantu abadala abaqhekekileyo bentamo ye-femoral, eyona ndlela ixhaphakileyo yokulungiswa kwangaphakathi kukubunjwa 'kunxantathu ojikiweyo' ngezikrufu ezithathu. Izikrufu ezibini zibekwe kufutshane nentamo yangaphambili nengasemva yentamo ye-femoral, kwaye esinye isikrufu sibekwe ngezantsi. Ipateni ye-'3-screw' iyabonwa.
"I-medial circumflex femoral artery yeyona nto iphambili ekunikezelweni kwegazi kwintloko yesifazane. Xa izikrufu zibekwe 'in-out-in' ngaphezu kwendawo yangasemva yentamo ye-femoral, ibeka umngcipheko wokulimala kwe-iatrogenic ye-vascular, enokuthi ibeke esichengeni ukunikezelwa kwegazi kwintamo ye-femoral kwaye, ngenxa yoko, ichaphazela ukuphulukiswa kwamathambo."
Ukuthintela ukwenzeka kwento ethi 'in-out-in' (IOI), apho izikrufu zidlula kwi-cortex yangaphandle yentamo ye-femoral, ziphume kwi-cortical bone, kwaye ziphinde zingene kwintamo ye-femoral nentloko, abaphengululi ekhaya nakwamanye amazwe baye basebenzisa iindlela ezahlukeneyo zokuhlola ezincedisayo. Ukudakumba ethanjeni Ngokufunda ubudlelwane phakathi kwezikrufu ezibekwe ngasentla kwenkalo yangasemva yentamo yowesifazane kunye ne-acetabulum kwimbono ye-anteroposterior, umntu unokuqikelela okanye avavanye umngcipheko we-screw IOI.
▲ Umzobo ubonisa umfanekiso we-cortical bone we-acetabulum kwimbono ye-anteroposterior ye-joint hip.
Uphononongo lubandakanya izigulane ze-104, kwaye ubudlelwane phakathi kwethambo le-cortical ye-acetabulum kunye ne-screws yangasemva ihlolwe. Oku kwenziwa ngokuthelekisa kwi-X-rays kwaye kuncediswe ngokwakhiwa kwakhona kwe-CT emva kokusebenza ukuvavanya ubudlelwane phakathi kwezi zibini. Phakathi kwezigulane ze-104, i-15 ibonise into ecacileyo ye-IOI kwi-X-rays, i-6 yayinedatha ye-imaging engaphelelanga, kwaye i-10 yayinezikrini ezibekwe ngokusondeleyo phakathi kwentamo ye-femoral, eyenza ukuvavanya kungasebenzi. Ngoko ke, amatyala angama-73 asemthethweni afakwe kuhlalutyo.
Kwiimeko ezihlalutyiweyo ze-73, kwi-X-rays, iimeko ze-42 zinezikhonkwane ezibekwe ngaphezu kwethambo le-cortical ye-acetabulum, ngelixa iimeko ze-31 zinezikhonkwane ezingezantsi. Ukuqinisekiswa kwe-CT kubonise ukuba i-IOI phenomenon yenzeke kwi-59% yamatyala. Uhlalutyo lwedatha lubonisa ukuba kwii-X-rays, izikrufu ezibekwe ngaphezu kwethambo le-cortical ye-acetabulum zinemvakalelo ye-90% kunye ne-specific ye-88% ekuqikeleleni i-IOI phenomenon.
▲ I-Case One: I-hip joint X-ray kwimbono ye-anteroposterior ibonisa izikrufu ezibekwe ngaphezu kwethambo le-cortical ye-acetabulum. Iimbono ze-CT coronal kunye ne-transverse ziqinisekisa ubukho be-IOI phenomenon.
▲Ityala lesibini: I-X-ray edibeneyo ye-Hip kwimbono ye-anteroposterior ibonisa izikrufu ezibekwe ngaphantsi kwethambo le-cortical ye-acetabulum. Iimbono ze-CT coronal kunye ne-transverse ziqinisekisa ukuba i-screws yangasemva ingaphakathi ngokupheleleyo kwi-cortex yamathambo.
